Abstract
A method is provided for enhancing yield of a cook-in packaged meat product that includes first providing an adhering cook-in container including a flexible thermoplastic envelope being substantially conformable to a contained meat product and having an inner surface of a selectively irradiated ionomer of a metal salt neutralized copolymer of ethylene and acrylic acid or methacrylic acid, then conforming the container about a selected meat product and cooking the packaged product, whereupon the inner surface of the envelope bonds to the meat product to substantially prevent cook-out of fluids. An associated cook-in container is also provided.
Claims8
A method for enhancing yield of a cook-in packaged meat product, comprising:
- (a) providing an adhering cook-in container including a flexible thermoplastic envelope being substantially conformable to a contained meat product and having an inner meat contacting surface of an ionomer of a metal salt neutralized copolymer of an olefin and a carboxylic acid, said ionomer, while positioned as the inner surface of a flattened tube, having been treated with ionizing radiation to a dosage sufficient to cause bonding with a meat product positioned in contact therewith during cooking of said meat product;
- (b) conforming said container about a selected meat product;
- and
- (c) cooking the packaged product, whereupon said inner surface bonds to said meat product to substantially prevent cook-out of fluids therefrom.
